The U.S. Federal Bureau of Investigation (FBI) disclosed today that it infiltrated the world’s second most prolific ransomware gang, a Russia-based criminal group known as ALPHV and BlackCat. The FBI said it seized the gang’s darknet website, and released a decryption tool that hundreds of victim companies can use to recover systems. Meanwhile, BlackCat responded by briefly “unseizing” its darknet site with a message promising 90 percent commissions for affiliates who continue to work with the crime group, and open season on everything from hospitals to nuclear power plants. A slightly modified version of the FBI seizure notice on the BlackCat darknet site (Santa caps added). Whispers of a possible law enforcement action against BlackCat came in the first week of December, after the ransomware group’s darknet site went offline…

One of the cybercrime underground’s more active sellers of Social Security numbers, background and credit reports has been pulling data from hacked accounts at the U.S. consumer data broker USinfoSearch, KrebsOnSecurity has learned. Since at least February 2023, a service advertised on Telegram called USiSLookups has operated an automated bot that allows anyone to look up the SSN or background report on virtually any American. For prices ranging from $8 to $40 and payable via virtual currency, the bot will return detailed consumer background reports automatically in just a few moments. USiSLookups is the project of a cybercriminal who uses the nicknames JackieChan/USInfoSearch, and the Telegram channel for this service features a small number of sample background reports, including that of President Joe Biden, and podcaster Joe Rogan. The data…

Prosecutors in Finland this week commenced their criminal trial against Julius Kivimäki, a 26-year-old Finnish man charged with extorting a once popular and now-bankrupt online psychotherapy practice and thousands of its patients. In a 2,200-page report, Finnish authorities laid out how they connected the extortion spree to Kivimäki, a notorious hacker who was convicted in 2015 of perpetrating tens of thousands of cybercrimes, including data breaches, payment fraud, operating a botnet and calling in bomb threats. In November 2022, Kivimäki was charged with attempting to extort money from the Vastaamo Psychotherapy Center. In that breach, which occurred in October 2020, a hacker using the handle “Ransom Man” threatened to publish patient psychotherapy notes if Vastaamo did not pay a six-figure ransom demand. Vastaamo refused, so Ransom Man shifted to extorting…

Microsoft today released updates to fix more than five dozen security holes in its Windows operating systems and related software, including three “zero day” vulnerabilities that Microsoft warns are already being exploited in active attacks. The zero-day threats targeting Microsoft this month include CVE-2023-36025, a weakness that allows malicious content to bypass the Windows SmartScreen Security feature. SmartScreen is a built-in Windows component that tries to detect and block malicious websites and files. Microsoft’s security advisory for this flaw says attackers could exploit it by getting a Windows user to click on a booby-trapped link to a shortcut file. Kevin Breen, senior director of threat research at Immersive Labs, said emails with .url attachments or logs with processes spawning from .url files “should be a high priority for threat hunters…

In the summer of 2022, KrebsOnSecurity documented the plight of several readers who had their accounts at big-three consumer credit reporting bureau Experian hijacked after identity thieves simply re-registered the accounts using a different email address. Sixteen months later, Experian clearly has not addressed this gaping lack of security. I know that because my account at Experian was recently hacked, and the only way I could recover access was by recreating the account. Entering my SSN and birthday at Experian showed my identity was tied to an email address I did not authorize. I recently ordered a copy of my credit file from Experian via annualcreditreport.com, but as usual Experian declined to provide it, saying they couldn’t verify my identity. Attempts to log in to my account directly at Experian.com…

Last week, KrebsOnSecurity broke the news that one of the largest cybercrime services for laundering stolen merchandise was hacked recently, exposing its internal operations, finances and organizational structure. In today’s Part II, we’ll examine clues about the real-life identity of “Fearless,” the nickname chosen by the proprietor of the SWAT USA Drops service. Based in Russia, SWAT USA recruits people in the United States to reship packages containing pricey electronics that are purchased with stolen credit cards. As detailed in this Nov. 2 story, SWAT currently employs more than 1,200 U.S. residents, all of whom will be cut loose without a promised payday at the end of their first month reshipping stolen goods. The current co-owner of SWAT, a cybercriminal who uses the nickname “Fearlless,” operates primarily on the cybercrime…

Posted by Nataliya Stanetsky, Android Security and Privacy Team Keeping Google Play safe for users and developers remains a top priority for Google. As users increasingly prioritize their digital privacy and security, we continue to invest in our Data Safety section and transparency labeling efforts to help users make more informed choices about the apps they use. Research shows that transparent security labeling plays a crucial role in consumer risk perception, building trust, and influencing product purchasing decisions. We believe the same principles apply for labeling and badging in the Google Play store. The transparency of an app’s data security and privacy play a key role in a user’s decision to download, trust, and use an app. Highlighting Independently Security Tested VPN Apps Last year, App Defense Alliance (ADA) introduced…
